- Internal intercostal musclesMusculi intercostales interniThe internal intercostals form the middle layer of muscle between the ribs, used mainly in forced breathing out.
- Internal jugular veinVena jugularis internaThe large deep vein of the neck, running in the carotid sheath from the jugular foramen down to the base of the neck.
- Internal thoracic arteryArteria thoracica internaA paired branch of the subclavian artery that descends just inside the front chest wall beside the sternum.
- Internal thoracic veinsVenae thoracicae internaePaired veins behind the costal cartilages, beside the sternum, that drain the anterior chest wall into the brachiocephalic veins.
- Interosseous membrane of forearmMembrana interossea antebrachiiA strong fibrous sheet stretched between the radius and ulna, dividing the forearm into front and back compartments.
- Interosseous membrane of legMembrana interossea crurisA thin fibrous sheet joining the interosseous borders of the tibia and fibula and dividing the front of the leg from the back.
- Interosseous metacarpal ligamentsLigamenta metacarpea interosseaShort strong ligaments between the bases of neighbouring metacarpal bones in the palm, binding the second to fifth metacarpals together.
- Interosseous sacro-iliac ligamentLigamentum sacroiliacum interosseumA mass of short, very strong fibres filling the gap between the sacral and iliac tuberosities behind the sacro-iliac joint.
- Interpectoral nodesNodi interpectoralesA few small lymph nodes lying in the fatty plane between pectoralis major and pectoralis minor on the front of the chest.
- Interpeduncular fossaFossa interpeduncularisA diamond-shaped hollow on the base of the brain between the cerebral peduncles, behind the optic chiasm and in front of the pons.
- Interpubic discDiscus interpubicusThe thick plate of fibrocartilage in the pubic symphysis, binding the right and left pubic bones together at the front of the pelvis.
- Intersesamoid ligamentLigamentum intersesamoideumA short transverse band beneath the head of the first metatarsal that ties together the paired sesamoids of the great toe.
- Interspinales colli musclesMusculi interspinales colliThe interspinales colli are short paired muscles bridging the spinous processes of neighbouring neck vertebrae, from the axis down to T1.
- Interspinales lumborum musclesMusculi interspinales lumborumThe interspinales lumborum are short paired muscles joining the spinous processes of neighbouring lumbar vertebrae on each side of the interspinous ligament.
- Interspinales thoracis musclesMusculi interspinales thoracisThe interspinales thoracis are small, inconstant muscles joining adjacent thoracic spinous processes, found mainly at the top and bottom of the thoracic spine.
- Interspinous ligamentsLigamenta interspinaliaThin membranes filling the gaps between neighbouring spinous processes, from the base to the tip of each process.
- Intertransverse ligamentsLigamenta intertransversariaFibrous bands stretching between the transverse processes of neighbouring vertebrae on each side of the spine.
- Intervertebral discsDisci intervertebralesThe fibrocartilage pads between the vertebral bodies from C2 to the sacrum, each a ring of tough fibres around a soft core.
- Intra-articular ligament of head of ribLigamentum intraarticulare capitis costaeA short flat band inside the joint of a rib head, tying the crest between its two facets to the intervertebral disc.
- Intraglandular parotid nodesNodi parotidei intraglandularesLymph nodes embedded within the substance of the parotid salivary gland, in front of and below the ear.
- Intraparietal sulcusSulcus intraparietalisA long groove across the outer face of the parietal lobe that divides the superior from the inferior parietal lobule.
- Intrapulmonary nodesNodi intrapulmonalesSmall lymph nodes inside the substance of the lung, lying along the bronchi and branches of the pulmonary artery where the airways divide.
- Intrarenal arteries of left kidneyArteriae intrarenales renis sinistriThe branching tree of arteries inside the left kidney, from the segmental arteries at the hilum to the vessels feeding each glomerulus.
- Intrarenal arteries of right kidneyArteriae intrarenales renis dextriThe arteries within the right kidney, dividing in steps from the renal hilum down to the arterioles of each glomerulus.
